Working Principles

The N25Q256A33EF840E is based on the NAND flash memory technology. It stores data by trapping electrons in a floating gate, which can be electrically programmed and erased. The Serial Peripheral Interface (SPI) allows for high-speed communication between the chip and the host device. When data is read, the stored charge in the memory cells is measured to determine the logic state. During write operations, the floating gate is charged or discharged to store the desired data.

Detailed Application Field Plans

  • Embedded systems: Used for firmware storage in microcontrollers and IoT devices.
  • Consumer electronics: Enables data storage in smartphones, tablets, and digital cameras.
  • Automotive: Provides non-volatile memory for infotainment systems and instrument clusters.
  • Industrial automation: Used for program storage in PLCs and industrial control systems.
  • Networking equipment: Enables firmware storage in routers, switches, and network appliances.
